FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 438,337, dated October14, 1890.

Application filed March 19, 1890.

Serial No. 344,474. (No model.)

To all whom it may concern:

Be it known that I, CLAYTON WoLcorT, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inFasteners for the Meeting-Rails of Sashes, of which the following is aspecification.

My invention relates to improvements in fasteners for the meeting-railsof sashes; and the objects of my improvements are simplicity and economyin construction and efficiency in operation.

In the accompanying drawings, Figure 1 is a plan view of mysash-fastener and its keeper. Fig. 2 is a reverse plan view of saidfastener. Figs. 3 and at are horizontal sections of the cam-lever, therest of the fastener being shown in plan view, the parts beingrepresented in two different positions in said figures; and Fig. 5 is avertical section on line w m of Fig. 2, withthe cam-lever in elevation.

My invention is in the nature of an im provement upon the fastenerpatented to me May 29, 1888, No. 383,549, and has the same general form,especially in its external appearance.

A designates the base-plate having a boxlike elevation 6 at its middleportion, with a hole for the pivot-pin of the cam-lever 7 Upon thisbox-like elevation there is pivoted the latch-plate 8, within which thesliding latch 9 is mounted and upon which the camlever 7 is placed, withits pivot-pin 10 extend- 3 5 ing through the centrahhole in the top ofthe box-like elevation 6, the end of said pin being riveted to hold theparts together, all sub stantially the same as in my aforesaid patent.

In the top of the box-like elevation 6 there is a segmental slot 11,Fig. 2, one end of which is provided with an enlargement to form theshoulder 12, which stands substantially transversely to the length ofsaid segmental slot. The latch 9, as in my former patent, 5 not onlyswings as on a pivot with the camlever and the latch-plate, but it alsohas a longitudinal movement within said plate. Its widest end lieswithin the latch-plate and is provided with substantially a rectangular50 and central opening, through which the pivot pin passes and in theupper side of which the cam13 of the cam-lever works. This opening inthe latch-lever is recessed on one side at its upper edge, so as to forma plain shoulder 14: outside of the central opening, and an inclinedshoulder or face 15 near the forward end. The under side of said latchis provided with a locking-pin 16, which passes through a short slot inthe bottom of the latchplate into a position for working in the seg- Imental slot 11 and its enlargement. The under side of the latch-plate isprovided with a stop-pin 17 for traversing in the segment of a circlethe segmental slot 11. The cam 13 is form ed with a driving-face whichstands substantially in a plane passing through'the axis of said cam,and upon the reverse side of said face it is rounded off to act like awiper. I

In Figs. 1, 2, 3, and 5 the cam-lever is turned into a position atrightangles with the latch, and therefore the latch is drawn toward thefront for drawing the two rails of the sash together and locking thelatch in position, as will hereinafter be described.

To unlock or disengage the fastener, the cam-lever is swung into theposition represented in Fig. 4:, where it stands substantially inalignment with the latch 9. In moving into this position thedriving-face of the cam engages the shoulder 14 on the latch and forcesthe latch outwardly, as shown in Fig. 4:, when it is prevented frommoving farther in that direction by striking the outer wall of thelatch-plate. A continued movement of the cam-lever for another quarterof a circle will withdraw the latch from the keeper, and the combinedlatch and cam-lever will stand ina position parallel to the length ofthe baseplate A, entirely out of the way of the sasho rails. In thisposition the locking-pin 16 on the latch is carried to that end of thesegmental slot which is on the left-hand side in Fig. 2 and acts as astop for limiting the movement of the cam-lever in that direction. 5 Inorder to again lock the fastener, the camlever is turned back again intothe position illustrated in Figs. 1, 2, 3, and 5. In the early part ofsaid movement the friction of the parts will carry the latch with thecam-lever I00 with but little or no change in the longitudinal movementof the latch until the'latch is brought into engagement with the keeper.The cam 13 then moves a little without moving the latch-boltlongitudinally; but soon its rounded or wiping face engages the inclinedface 15 and forces said latch lengthwise from the position shown in Fig.4 to that shown in Fig. 3, when the further movement of the cam-lever isarrested by the stop-pin 17 reaching the end of the segmental slot 11,as shown in Fig. 2. During this longitudinal movement of the latch thelocking-pin 16 moves from its segmental path into position by the sideof the shoulder 12, as also shown in Fig. 2, whereby the latch is lockedagainst being moved in either direction by direct pressure upon theouter end of the latch, the stop-pin 17 locking it against movingin onedirection and the locking-pin 16 against movement inthe oppositedirection. By the employment of the stop-pin 17, which moves only in acircular path, there is no frictional or rubbing action of thelocking-pin 16 011 the base-plate when saidpin is moving into itsposition by the side of the shoulder 12.

I claim as my invention 1. The combination of the base-plate A, thelatch-plate 8, pivoted on said base-plate, the latch 9, mounted to slidelongitudinally within said latch-plate and having a hooked outer end,and an inner end within said latchplate, having a central opening, withthe inclined face 15 at that end of said opening which is farthest fromsaid hooked outer end, and the drawing-shoulder 14 near the middleportion of that side of said opening which stands substantially at rightangles to the side having said inclined face, and the cam-lever providedwith the cam 13, having on one side a substantially radial face and uponthe other side a wiping-face,substantially as described, and for thepurpose specified.

2. In a fastener of the class described,hav ing base-plate, latch-plate,latch, and camlever, the stop-pin 17 on the latch-plate, and thelocking-pin 16 on the latch, operating in connection with the segmentalslot 11 and shoulder 12 of the base-plate, substantially as described,and for the purpose specified.
